Minor suits score 20pts, and
major suits 30pts for each level ofa contract made.For example
3♣ bid and made scores 3 x 20 = 60pts. Overtricks score as per the
contract. If you fail to make the contract, your opponents score 50pts for
each under-trick.

In Rubber bridge, pts scored
for making the contract go BELOW the LINE on the score pad. Overtricks,
bonuses, and under-tricks go above the line. A ‘GAME’ is 100pts. Two games
make a rubber. A PART SCORE is any contract scoring less than 100 pts

Bonuses are scored for making
rubber ( 700pts for 2 games where the opponents have not scored a game,
else 500pts), and for bidding and making a slam.

If the contract is DOUBLED, and
made the score doubles , plus an insult bonus of 50pts. If you fail to
make the contract, the first under-trick is 100pts, subsequent 200 pts
each.

When you have scored a game,
you are said to be vulnerable.

Bridge drives and duplicate
score in a different way. The bonuses are added to each hand. A part score
= 50pts, game 300pts. More(500) if you are vulnerable. Slams score an
extra 500 pts on top of the game bonus.
